[ic] Passing parameters to usertags

[Interchange User]

Hi folks,

	I'm having some trouble with (what I think is) a very basic question 
on a custom usertag.  I have the following tag, which I am constructing 
to dynamically build a navbar on an IC 4.9.7 site.  The problem I am 
having is getting parameters passed to the subroutine.  I thought if I 
wanted to access a section of the web site called "search" under a page 
called "database" (where "section" and "page" are just terms I'm using 
to describe different parts of my site) I could do something like

	[test_nav page=database section=search]

and have the variables $page and $section be accessible to me, but that 
doesn't appear to work.

	So instead, I started calling my tag with positional parameters, like 
so:

	[test_nav database search]

	This works, sort of.  I am able to shift arguments off the @_ 
variable, but everything after the tag name (eg: "database search") 
gets pulled off as one variable, whereas I expected this to come off as 
a list.  In my subroutine, I thought I could do

	my ($page, $section) = @_;

but that doesn't work, and instead I have to do the following:

UserTag test_nav Interpolate
UserTag test_nav Routine <<ENDTEST
sub {
	my $nav;
	my $page;
	my $section;
	my $args = shift;		# Gets arguments that were passed, as a single 
string?
	($section, $page) = split / /, $args;
	
	#	do stuff with $section and $page...

}
ENDTEST


	Is this normal?

Thanks,

Peter
